Unfortunately, this promotion is valid within US only, despite the fact that their twitter fans come from all over the world. What a shame!
I am still waiting for the day that nail polishes could be shipped freely everywhere, no border, no limit. I have missed out Zoya’s Polish Exchange, and 2 twitter promotions already. Why is it so hard to be a polish addict?
I don’t know whether it works with the Studio Line shadows though.
Have fun!
